Next, FIG. 4 is illustrated.

FIG. 4 is a view of utilizing a remote control device according to anembodiment of the present disclosure.

FIG. 4(a) illustrates that a pointer 205 corresponding to the remotecontrol device 200 is displayed on the display 180.

A user can move or rotate the remote control device 200 vertically orhorizontally. The pointer 205 displayed on the display 180 of thedisplay device 100 corresponds to a movement of the remote controldevice 200. Since the corresponding pointer 205 is moved and displayedaccording to a movement on a 3D space as show in the drawing, the remotecontrol device 200 can be referred to as a spatial remote controldevice.

FIG. 4(b) illustrates that if a user moves the remote control device200, the pointer 205 displayed on the display 180 of the display device100 is moved to the left according to the movement of the remote controldevice 200.

Information on a movement of the remote control device 200 detectedthrough a sensor of the remote control device 200 is transmitted to thedisplay device 100. The display device 100 can calculate the coordinatesof the pointer 205 from the information on the movement of the remotecontrol device 200. The display device 100 can display the pointer 205to match the calculated coordinates.

FIG. 4(c) illustrates that while a specific button in the remote controldevice 200 is pressed, a user moves the remote control device 200 awayfrom the display 180. Thus, a selection area in the display 180corresponding to the pointer 205 can be zoomed in and displayed larger.

On the contrary, when the user moves the remote control device 200 toapproach the display 180, the selection area in the display 180corresponding to the pointer 205 may be zoomed out and reduced.

On the other hand, if the remote control device 200 is moved away fromthe display 180, a selection area can be zoomed out and if the remotecontrol device 200 is moved closer to the display 180, a selection areacan be zoomed in.

Additionally, if a specific button in the remote control device 200 ispressed, recognition of a vertical or horizontal movement can beexcluded. In other words, if the remote control device 200 is moved awayfrom or closer to the display 180, the up, down, left, or right movementcannot be recognized and only the back and forth movement can berecognized. While a specific button in the remote control device 200 isnot pressed, only the pointer 205 is moved according to the up, down,left or right movement of the remote control device 200.

Moreover, the moving speed or moving direction of the pointer 205 cancorrespond to the moving speed or moving direction of the remote controldevice 200.

Furthermore, a pointer in this specification means an object displayedon the display 180 in response to an operation of the remote controldevice 200. Accordingly, besides an arrow form displayed as the pointer205 in the drawing, various forms of objects are possible. For example,the above concept includes a point, a cursor, a prompt, and a thickoutline. Then, the pointer 205 can be displayed in correspondence to onepoint of a horizontal axis and a vertical axis on the display 180 andalso can be displayed in correspondence to a plurality of points such asa line and a surface.
